Global carbon emissions from fossil fuels have not been decreasing over the past years, and the effect on global climate is increasingly noticeable. Carbon dioxide released into the atmosphere should be equal to the amount consumed, so that the concentration of CO2 can remain unchanged to achieve eco-environmental stability. A promising approach to mitigates carbon dioxide levels is to electrochemically reduce CO2 to value-added chemicals or fuels. The conversion of waste CO2 gas into hydrocarbons is an efficient way of utilization and recycling of carbon sources. The CO2 electroreduction system can be employed for practical application as it is moderate and controllable, and the products of electrochemical reduction can be adjusted by reaction parameters, such as potential, reaction temperature, electrolyte, electrocatalyst, and so on. In this work we synthesized mesoporous Cu films by polymeric micellization on carbon paper via electrochemical deposition to increase surface area and consequently the exposure to active sites where CO2 can be converted. The deposition of Cu showed a good porous structure, indicating the use of polymeric micelles was effective.
